CATTLE-STANGHION.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed May 29, 1908. Serial No. 435,737.

T all whom it may concern:

Be it known that I, citizen of the Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Cattle-Stanchions, of which the following is a specification.

This invention relates to cattle-stanchions and has for its object to provide improved means for releasing the movable stanchionbars.

The invention consists of a novel arrangement and combination of parts to be hereinafter described and claimed, reference being had to the accompanying drawings, in which,-

Figure 1 is an elevation; Fig. 2 is a plan view; Fig. 3 is an elevation of that portion of the stanchion extending at an angle to the one shown in Fig. 1; Figs. 4: and 5 are details of the late Referring specifically to the drawings, the stanchion has the usual stationary bars 7 secured between longitudinal strips 8 at the top thereof and similar strips 9 at the bottom, the latter strips being suitably secured to the floor of the shed. Between the strips 8 and 9 are pivoted the movable bars 10, said bars being pivoted at their lower ends to the strips 9, as indicated at 11. The movable bars 10 are each locked in operative position by a latch comprising a forked plate 12 the two branches of which have eyes 13 receiving staples 14: which are driven into the upper edge of the strips 8, whereby the latches are hinged to said strips. The plate 12 has a hook 13 which is adapted to engage the bar 10 and hold the same in upright position to secure the animal. Above the latches is arranged a cable 14 for operating the latches, the cable being connected to the latches by chains 15. On the back of the latches are lugs 16 having eyes 17 for attachment of one end of the chains, the other ends of the chains being connected to the cable by means of clamps 18. One end of the cable 14: is made fast to one arm 19 of a bell crank lever fulcrumed on a bracket 20 secured to a post 21, the other arm of the lever having a handle 22. The lever is provided with a pawl-andratchetmechanism 23 for locking the same. The other end of the cable is connected to an arm 24 pivoted at 25 to a bracket 26 mounted on a post 27.

CHRISTIAN NonLin, United States, residlng at 1 To the arm 2 1 1s connected a spring 25 a l l The arms 19 and 2% l swing in unison, in order that all parts of the cable may rise and lower uniformly. and on the bracket 20 is a stop 26 which is engageable by the arm 19. To prevent the cable from sagging, the stanchion-frame is provided at regular intervals with posts 27 at the top of which are mounted pulleys 28 on which the cable rests when it is in lowered position.

In the drawing is shown a stanchion which is built angular, in view of which means must be provided for changing the direction of the cable 1 1. This is accomplished by means of a guide pulley 29 lo cated at the corner of the stanchion-sections, over which pulley the cable travels. The pulley frame has eyes whereby it is slidably mounted on rods mounted on posts 31 at the corner of the stanchion-sections. This construction permits the pulley 29 to slide up and down and follow the cable 1 1 when it is raised and lowered, to

operate the latches 12.

To release the animals, the arm 19 is swung in a direction to elevate the cable 1 1-. and is locked by the pawl-and-ratchet mechanism 23. hen the cable rises a pull on the chain 15 is had, which liits the latches 12, whereby the bars 10 are released, and they are then free to swing on their pivots in a direction to release the animals. To look the bars 10 the arm 19 is released, whereupon the spring 25 pulls the cable 14: in a direction to lower it, which slackens the chains 15, and the latches then drop back to engage the bars. The stop '26 limits the downward swing of the cable. The bars 10 have beveled edges 32, so that when the latches are in lowered position they will automatically engage the bars 10 when they are swung into operative position. The bars 10 can also be released independently by reason oi the flexible connection between the latches and the cable, so that any animal may be released without releasing all.

The releasing mechanism herein described is simple in construction and reliable in operation; it has no complicated parts to get out of order, and in case of necessity, a quick release of all the animals is assured.

I claim:

In a cattle-stan.chion, the combination with the movable bars thereof, of a latch for each of said and means for swinging the arms in the opposite direction to lower said connection.

In testimony whereof I aflix ture, in presence of two witnesses.
